Objective To analyze the total cost and clinical effectiveness of internal fixation and hemiar-throplasty in the treatment of femoral neck fracture for the elderly. Methods From October 2013 to May 2015,85 patients above 60-year old who were diagnosed as displaced femoral neck fracture and received operation in our hospital. All the patients were divided into internal fixation(IF)group and hemiarthroplasty(HA)group respec-tively. There were 40 cases in the IF group and 45 cases in the HA group. The total cost associated with fracture in a year was collected by medical record ,telephone interview and standard methods. At the last follow-up ,we ap-plied Harris scores to evaluate the clinical outcome for each group. Results All the patients completed the operation successfully. During 1 year follow-up the total cost in the IF group was less than that in the HA group including higher primary hospitalization cost and less post-discharge cost. The total cost was 44,556.1 Yuan in the IF group and 72,198.0 Yuan in the HA group respectively. The data showed that the total cost of HA was 1.6 times higher than that of IF. At the last follow-up the mean Harris scores was 71.1 ± 12.1 in the IF group and 74.3 ± 10.3 in the HA group while the EQ-5D index was 0.74 ± 0.15 and 0.76 ± 0.13 respectively which showed no significant differ-ence(P > 0.05). Conclusions Both internal fixation and hemiarthroplasty have effective treatment for elderly pa-tients with femoral neck fracture. Compared to hemiarthroplasty IF can provide similar clinical effectiveness with less total cost. Therefore IF may contribute to decrease the economic burden for elderly patients in China.

Objective (1) To investigate the glucose and lipid metabolism 6-12 weeks after delivery in women with hyperglycemia during pregnancy. (2) To find out factors associated with the prognosis of women with hyperglycemia during pregnancy. (3) To investigate the feasibility of the diagnostic criteria set by the International Association of Diabetes and Pregnancy Study Group according to the follow-up data of women with hyperglycemia in pregnancy. Methods Clinical data of 262 women with hyperglycemia during pregnancy delivered in our hospital from January 1, 2007 to December 31, 2009 were collected. All patients underwent oral glucose tolerance test (OGTT) at 6-12weeks after delivery. They were divided into two groups according to the postnatal status of glucose and lipid metabolism. Multivariate Logistic regression model was used to analyze the factors affected glucose and lipid metabolism after 6-12 weeks of delivery. Results (1) Among the 262 women, 92(35.1%) were reported with abnormal glucose metabolism at 6-12 weeks of delivery, including one (0. 4 % ) woman with impaired fasting glucose, 81 (30. 9 % ) with impaired glucose tolerance, 4( 1.5 % )with impaired fasting glucose+impaired glucose tolerance and 6 (2. 3%) with diabetes mellitus.glucose levels in OGTT (OGTT 2hPG and the OGTT 3hPG) were risk factors for postpartum 0. 181-0. 918)]. (3) All markers of lipid metabolism were detected in 250 women with hyperglycemia during pregnancy at 6-12 weeks after delivery, the rate of abnormal postnatal lipid metabolism was 63.2%(158/250). In the abnormal group (n= 174), the most common abnormal marker was hypercholesterolemia (n = 126, 50. 4 % ), followed by high levels of low-density lipoprotein-cholesterol (n = 102, 40. 8 %), hypertriglyceridemia (n= 60, 24. 0 %) and low levels of high-density lipoproteincholesterol (n= 11, 4. 4 %). (4) Logistic regression model showed that elevated OGTT 2hPG was the risk factor for postpartum abnormal glucose metabolism [OR= 1. 364 (95%CI: 1. 063-1. 751)], while 0. 169-0. 851)]. Conclusions Women with hyperglycemia during pregnancy are more likely to present with abnormal glucose and lipid metabolism which commonly coexisted with insulin resistance.The risk factors for the postpartum abnormal glucose metabolism in mothers with hyperglycemia during pregnancy include early diagnosis, OGTT 2hPG and OGTT 3hPG, while the protective factor is breastfeeding. The risk factor for the postpartum dyslipidaemia in mothers with hyperglycemia during pregnancy is OGTT 2hPG, while the protective factor is high-density lipoprotein-cholesterol level in pregnancy.

Objective To investigate the outcomes of increased gestational diabetes mellitus (GDM) and the influencing factors after the implementation of the new GDM diagnostic criteria.Methods A total of 1 439 GDM women who delivered in the Peking University First Hospital between May 1,2011 and December 31,2012 were studied and divided into two groups.Group Ⅰ included the women who met the new GDM diagnostic criteria (fasting plasma glucose and 1 or 2 h plasma glucose levels for 75-g oral glucose tolerance test performed between 24 and 28 weeks of gestation were no less than 5.1,10.0 and 8.5 mmol/L),but did not meet the National Diabetes Data Group (NDDG) criteria;and Group Ⅱ included the women who met the NDDG criteria only.Women in Group Ⅰ were further divided into two subgroups according to whether attending the one-day GDM outpatient visit.Follow-up rate and detecting rate of abnormal glucose metabolism at 6-12 weeks after delivery were analyzed.Chi-square test,t test and multivariate Logistic analysis were used for statistical analysis.Results There were 849 GDM women in Group Ⅰ (59.0％,849/1 439) and 590 (41.0％,590/1 439) in Group Ⅱ.The follow-up rate in group Ⅰ was lower than in group Ⅱ [25.9％(220/849) vs 32.0％(189/590),x2=6.112,P=0.013].There were five cases of impaired fasting glucose and 34 impaired glucose tolerance in Group Ⅰ;and four cases of impaired fasting glucose,56 impaired glucose tolerance,eight impaired fasting glucose tolerance with impaired glucose tolerance and five diabetes mellitus in Group Ⅱ;there were significant differences [17.7％(39/220) vs 38.6％(73/189),x2=33.810,P=0.000].(2) In Group Ⅰ,the increased glucose level at 2 h in oral glucose tolerance test during pregnancy (OR=1.547,95％CI:1.038-2.306,P=0.032) and family history of diabetes mellitus (OR=1.879,95％CI:1.066-3.313,P=0.020) were risk factors for postpartum abnormal glucose metabolism,while breast-feeding was a protective factor (OR=0.290,95％CI:0.092-0.914,P=0.035).(3) In group Ⅰ,the follow-up rate in those who attended the one-day GDM outpatient visit was higher than those who did not [30.7％(185/603) vs 14.2％(35/246),x2=23.780,P=0.000],but the detecting rate of postpartum abnormal glucose metabolism were similar in women attending the one-day GDM outpatient visit and those not attending [17.8％(33/185) vs 17.1％(6/35),x2=0.020,P=0.887].Conclusions Increased GDM women still have glucose metabolism abnormality after delivery,especially those who have higher glucose level at 2 h after glucose intake in 75 g oral glucose tolerance test during pregnancy and who have a family history of diabetes mellitus.The one day GDM outpatient visit may improve the follow-up rate for these women.

OBJECTIVETo determine the effect of AQP1 gene on facial nerve edema following injury through investigation of the relationship between the expression of AQP1 gene and Schwann cells swelling.

METHODSThe AQP1 expression in Schwann cells of mouse facial nerve tissues was detected by immunofluorescent staining. The transgenic protocol by lentivirus transduction was used to specifically upregulate AQP1 expression in Schwann cells. Lenti-AQP1 and CTRL (empty vector) transduced cells were observed during gene overexpression every 24 h for 6 days by using phase contrast microscopy. Cell volume of CTRL and Lenti-AQP1 treated cells was measured daily from the day of treatment, through day 6.

RESULTSSchwann cell primary cultures maintained a high level of AQP1 water channels, representing an ideal cell model to study the role of AQP1 in the facial nerve. The expression of AQP1 mRNA and protein in Schwann cells infected with the Lenti-AQP1 was increased significantly compared with CTRL lentivirus (P < 0.05). Lenti-AQP1 caused cell swelling in cultured Schwann cells, as validated by cell volume determinations (P < 0.01).

CONCLUSIONSAQP1 is an important factor responsible for the fast water transport of cultured Schwann cells. It plays an important role in facial nerve edema.
